PIPE

Application iled December 26, 1920. Serial No. 504,895.

This invention relates to new improvements in smoking pipes.

It is one of the objects of the invention to provide a smoking pipe which is so constructed that the saliva from the. mo-uth of the smoker cannot enter the bowl or tobacco receptacle of the pipe.

It is a further obj ect of the invention so to construct a smoking pipe that the smoke in l@ its passage from the bowl of the pipe to the discharge end of the stem thereof will be cooled.

t is a still further object of the invention, so to construct a. smoking pipe that the same may be easily cleaned.

A still further object of the invention resides in the provision of means which is removably carried by the pipe for preventing the entrance of saliva to the bowl of the pipe.

With the above and other objects in view, reference is had to the accompanying drawing, in which,

Figure 1 is a longitudinal. sectional view of a pipe constructed in accordance with the present invention, Y

Figure 2 is a top plan view thereof showing the bowl in section and taken on the line 2-2 of Figure 1,

Figure 3 is a plan View of the removable portion of the stem.

Figure 4 is an enlarged detail sectional view taken on the line 4 4 of Figure 1.

Figure 5 is a detail sectional view taken on the line 5 5 of Figure 1.

Figure 6 is a bottom perspective view of the pipe bowl,

Figure 7 is a detail sectional View of a pipe bowl constructed in accordance with the present invention and showing the manner in which certain portions of the pipe bowl are formed,

Figure 8 is a detail bottom plan view of one of the elements which go to make up the pipe, and

Figure 9 is a perspective view of an implement employed for removing the plug.

Referring particularly to the drawing', the reference numeral 10 designates the pipe bowl, 11 designates the stein, and 12 designates the bit thereof. The bit may be of any and useful desired construction, and' suitably secured therein as at 13, there is a tube 14 which eX- tends from the forward end of the bit and which' has an enlarged portion 15 which is screw threaded as designated at 16. rlhis tube may be anchored within the bit 12 by knurling the same as indicated' at 17 in Figure 3, and the bit and tube are secured within the stem of the pipe by a screw threading operation.

The tube 14 has its forward end rounded C@ or tapered as at 18, and is provided with a plurality of longitudinally extending splits or the like 19, the purpose of which will be hereinafter described. The passage through the stem which is designated 2O is larger in diameter than the tube 14, and extends to the forward end of the lower section ofthe bowl, and passes through the bowl wall in the form of a. relatively small opening designated 21. The forward end of this passage is tapered as at 22 to conform to the tapered end 18 0f the tube 14, tie purpose of which taper will be hereinafter described.

ln carrying out the present invention, a passageway such as designated 24 in Figure 1 is bored from the bottom of the pipe bowl upwardly into the wall of said bowl and a ,plug member such as 25 is adapted to be inserted into this passageway 24. rlhe upper end of the passageway 24 is reduced as at 26, and 8U the plug 25 has still. further reduced oortion 27 which is adapted to be received within the reduced portion 26 of the passage 24 to provide a space 27 around the reduced end of the plug. The space 2'? has communica tion with the interior of the bowl 10 by means of a passageway such as 30 which may be formed by inserting a rotary circular tool 31 into the pipe bowl shown in Figure 7. and cutting through the wall4 thereof with said tool at such a location in. the wall of the pipe howl that the passage formed bv the tool will intersect the passage 24 at Lhe upper end thereof or at the lower end of the reduced portion 26 thereof, all as illustrated in Fig- 5" ure 7. Y

rlhe plug 25 has a passage 34 extending therethrough and said passage hascommuuication at its upper end with theV space 27 as best illustrated in Figure 4. Extending Cil through the plug at substantially right angles to the passage 34, there is a passage 36 and this passage 36 is adapted to receive the tube 14 as best illustrated in Figures 1 and 4.

By reference to Figure 4 it will be noted that when the pipe is completely assembled, the slits 19 will have communication with the passage 34 through the plug 25 and it is by means of these slits 19, the passage 34, the space 27, and the passageway that communication is established and the tube 14.

From the foregoing description, it will be apparent that saliva which enters the bit 12; and from whence it passes into the tube 14,

will be trapped in the forward end of the tube 14, and will not pass upwardly through the passage 34 and the space 27 to the interir of the bowl 10` during normal smoking of the pipe. Y

When it is desired to clean the bit and stem, it is only necessary to back olf the bit slightly with respect to the stem l1, when the free end of the stem will be open and a pipe cleaner may be passed through the bit 12, the tube 14 and onwardly through the opening 21 in the bow-l thus cleaning the tube and removing any deposits or sediment which may have collected therein. After the above cleaning operation has been carried out, the bit is again turned home and the tapered end of the tube 14 will engage the curved wall 22 heretofore mentioned and close the same together with the opening 21. This opening 21 however may not be entirely closed and in operation of the pipe a slight inflow of air at this point may result. rlhe inflow of air however will not be suiiicient to interfere with the perfect draft of the pipe, and will also have the added advantage of cooling the smoke.

Vilhen it is desired to clean the communieating passages between the bowl and the tube 14, the tube is entirely removed from the stem 11, or back out of the same sufliciently to permit of the end 18 thereof clearing the plug. The plug may then be removed, the passages cleaned and the plug likewise cleaned when it is again inserted into the passage 24 and the stem passed therethrough to the position illustrated in Figure 1.

For removing the plug 25, I provide a key which is best illustrated in Figure 6, and said key consists of a plug embracing portion 41 having hooked ends 42. These hooked ends are adapted to pass through longitudinally extending passages 43 in the plug 25 and into an annular channel 44, after which the key is slightly turned so that its projecting ends 42 engage beneath the flange 45 formed by the vannular channel 44. whereupon the plug may be freely or readily withdrawn from the passage 24 by the key 40.

From the foregoing it will be apparent between the bowl that the present invention provides a new and improved smoking pipe which will be sanitary, which may be readily cleaned, in which the saliva cannot enter the bowl and the contents thereof, and in which the eX- terior of the bowl is not disfigured by the peculiar arrangement of the parts within the pipe stem and bowl.

l/Vhile the invention has been herein illustrated in a preferred form, it is to be understood that the invention is not to be limited to the specific construction shown, and that it may be practiced in other forms without departing from the spirit thereof.

Having thus described the invention, what is claimed asy new, and what it is desired to secure by Letters Patent of the United States, is:

1. In a smokers appliance, a body having a bowl and a stem, said body having a bore extending through the bowl and stem, the

end portion of said bore within the bowl being reduced in diameter, 'a bit, a tubular member attached to said bit and positioned within said bore, one end portion of said tubular member being provided with a plurality of incisions extending lengthwise thereof and defining partly severed portions having tapering free ends for engaging the wall of the constricted portion of the bore.

2. In a smokers appliance, a body having a bowl and a stem, said body having a bore extending throughthe bowl and stem, the end portion of said bore within the bowl being reduced in diameter, a bit, a tubular member attached to said bit and positioned within said bore, one end portion of said tubular member being provided with a plurality of incisions extending lengthwise thereof and defining partly severed portions having tapering free ends for engaging the wall of the constricted portion of the bore, and a plug carried by said body and having means cooperating with the bore to establish communication between the bowl and the interior of said tubular member.

In testimony whereof I affix' my signature.
